Ceramic cutter added with coating powder, preparation method and application thereof
The invention relates to a ceramic cutter added with coating powder, a preparation method and application of the ceramic cutter. The ceramic cutter is prepared from the following raw materials in parts by volume: 5 to 15 parts of nano CaF2@SiO2 coating powder, 59 to 66 parts of Al2O3, 25.53 to 28.35 parts of TiC and 0.1 to 2 parts of MgO, wherein the volume ratio of Al2O3 to TiC is (5 to 8) to 3.Compared with a traditional ceramic cutter preparation method, the method of the invention has the following characteristics that a multi-time dispersion mode is adopted for solving the problem that nano-powder is prone to agglomeration. In order to prevent the structure of the coating powder from being damaged by an overlong ball milling process, when the nano-coating powder is added in the laterperiod of ball milling, the nano-coating powder is dispersed by adopting a dispersing agent and an ultrasonic dispersion mode and then is added into a ball milling tank, so that aggregation of the nano-coating powder is avoided, and the performance of the cutter is improved to a certain extent.
本发明涉及一种添加包覆粉体的陶瓷刀具及其制备方法和应用。所述陶瓷刀具的各原料的体积份数为纳米CaF2@SiO2包覆粉体5‑15份、Al2O359‑66份、TiC 25.53‑28.35份和MgO 0.1‑2份，Al2O3和TiC体积比的比例为5～8:3；与传统的陶瓷刀具制备方法相比，针对纳米粉体容易团聚的问题，采用了多次分散的方式。为了防止过长的球磨过程对包覆粉体的结构造成破坏，本发明在球磨后期加入纳米包覆粉体时，采用分散剂和超声分散的方式对纳米包覆粉体进行分散后加入球磨罐中。避免了纳米包覆粉体的聚集，从一定程度上提升了刀具性能。
